Peter Dillinger f4a02f2c52 Add hash_seed to Caches (#11391) 
Summary:
See motivation and description in new ShardedCacheOptions::hash_seed option.

Updated db_bench so that its seed param is used for the cache hash seed.
Made its code more safe to ensure seed is set before use.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/11391

Test Plan:
unit tests added / updated

**Performance** - no discernible difference seen running cache_bench repeatedly before & after. With lru_cache and hyper_clock_cache.
